This is not working properly here. Using 48khz with the above or higher sample rates I get many xruns from jackd and it is impossible to connect ardour. However if I use 44100/48000 with the default period size of 1024 then it takes jack a while to warm the card up (about 5-10 seconds) and then I get no xruns. However the sound quality is scratchy. -- Patrick Shirkey - Boost Hardware Ltd.
